What are the 4 characteristics of troposphere?
1) it is the first atmospheric layer closet to Earth's surface. 2) the troposphere is the region where weather occurs. 3)the temperature of troposphere decreases with an increase in height. 4)the troposphere makes up approximately 75% of Earth's atmosphere by mass.
What are the important characteristics of the troposphere of the stratosphere?
Calm & stable layer In the troposphere, the vertical air always flows upwards due to the presence of convection currents. But in the stratosphere, there is temperature inversion so there is no or little flow of vertical air current upwards. This is the reason for the calmness of the stratosphere.
What is the main characteristic of the tropopause?
The transition zone separating the troposphere from the stratosphere is called the tropopause. The tropopause is characterized by temperatures that stop decreasing and remain steady, before later increasing in the stratosphere. Temperature is a measure of the average kinetic energy in a substance.
What is troposphere and its importance?
The troposphere is the first and lowest layer of the atmosphere of the Earth, and contains 75% of the total mass of the planetary atmosphere, 99% of the total mass of water vapour and aerosols, and is where most weather phenomena occur.
Which characteristic describes the troposphere quizlet?
The troposphere is the lowest layer of Earth's atmosphere and site of all weather on Earth. The troposphere is bonded on the top by a layer of air called the troposphere, which separates the troposphere from the stratosphere, and on bottom by the surface of the Earth.
Why troposphere is very important for the meteorologists?
The troposphere is the layer of Earth's atmosphere that meteorologists watch most closely because it's where weather happens. Of all the layers that form the atmosphere, it's the closest to the ground, and all of Earth's landforms, including the highest mountains, exist within it.
What are 3 characteristics of the stratosphere?
(a) There are no clouds or weather changes so it is safe for air travel. (b) It extends from the top of troposphere up to 50 km above the surface of earth. (c) This layer has a band of ozone gas which protects us from sun's harmful ultraviolet rays.
Which of the characteristics below describes the troposphere?
The troposphere forms the lowest level of the Earth's atmosphere, extending down to the surface of the Earth. This layer also features the heaviest weight of all Earth atmosphere layers, comprising approximately 75 percent of the total atmospheric weight. The troposphere varies in thickness and height around the world.
Why is the troposphere the most important layer of the atmosphere give three points?
All the atmospheric phenomena such as rains, wind, clouds, etc. take place in this layer. Troposphere contains roughly 80% of the mass of Earth's atmosphere and it composed of composed of nitrogen (78%) and life giving gas oxygen (21%) with small concentrations of other trace gases.
What is a characteristic of each layer of the atmosphere?
The Earth's atmosphere is divided into four layers or 'spheres'. Each layer is characterized by a different gradient of the temperature as a function of altitude.
What is the characteristic of the atmosphere?
Earth's atmosphere is composed of about 78% nitrogen, 21% oxygen, and one percent other gases. These gases are found in layers (troposphere, stratosphere, mesosphere, thermosphere, and exosphere) defined by unique features such as temperature and pressure.
How does the troposphere protect life on earth?
The atmosphere protects life on earth by shielding it from incoming ultraviolet (UV) radiation, keeping the planet warm through insulation, and preventing extremes between day and night temperatures.
What are 3 facts about the troposphere?
Fact Sheet
- The troposphere contains 75% of the atmosphere's total mass.
- In either space or time the troposphere is not constant.
- Weather occurs in the troposphere.
- The troposphere is 10 miles from the equator.
- The troposphere is 5-7 miles above the poles.
- Does not contain ozone.
What are the characteristics of the thermosphere?
The thermosphere is the atmospheric region from ∼85 to ∼500 km altitude, containing the ionosphere. It is characterized by high temperature and large variability, in response to changes in solar ultraviolet radiation and solar-driven geomagnetic activity.
Why is troposphere the most important of all the layers of the atmosphere Brainly?
Troposphere the most important of all the layers of the atmosphere because here all the weather phenomena happens and oxygen nitrogen co2 are present .
Why is the troposphere the most important of all the layers of the atmosphere Class 11?
It is most important layer of the atmosphere because: Thickness of the troposphere is greatest at the equator because heat is transported to great heights by strong convectional currents. This layer contains dust particles and water vapour. All changes in climate and weather take place in this layer.
What happens in the troposphere?
We humans live in the troposphere, and nearly all weather occurs in this lowest layer. Most clouds appear here, mainly because 99% of the water vapor in the atmosphere is found in the troposphere. Air pressure drops, and temperatures get colder, as you climb higher in the troposphere.
What are the main characteristics of the thermosphere?
The thermosphere is the atmospheric region from ∼85 to ∼500 km altitude, containing the ionosphere. It is characterized by high temperature and large variability, in response to changes in solar ultraviolet radiation and solar-driven geomagnetic activity.
What are the characteristics of each layer of Earth?
The layers of Earth are:
- Crust – 5 to 70 km thick.
- Mantle – 2,900 km thick.
- Outer Core – 2,200 km thick.
- Inner Core – 1,230 to 1,530 km thick.

What are the 3 characteristics of atmosphere?
Answer. Answer: Earth's atmosphere is composed of about 78% nitrogen, 21% oxygen, and one percent other gases. These gases are found in layers (troposphere, stratosphere, mesosphere, thermosphere, and exosphere) defined by unique features such as temperature and pressure.
Why is troposphere the most important of all the layers of the atmosphere Class 11 geography?
It is most important layer of the atmosphere because: Thickness of the troposphere is greatest at the equator because heat is transported to great heights by strong convectional currents. This layer contains dust particles and water vapour. All changes in climate and weather take place in this layer.
Can you breathe in the troposphere?
Layers of the Earth's Atmosphere You breathe the air in the troposphere. Many airplanes fly in the stratosphere because it is very stable. Also, the ozone layer is there. Many rock fragments from space burn up in the mesosphere.
What are 2 facts about the troposphere?

What is an interesting fact about the troposphere?
This layer has the air we breathe and the clouds in the sky. The air is densest in this lowest layer. In fact, the troposphere contains three-quarters of the mass of the entire atmosphere. The air here is 78% nitrogen and 21% oxygen.
What is the importance of troposphere Class 7?
Answer: Troposphere is the densest layer of atmosphere that is composed of water vapour, dust particles and many other impurities. Due to this thickness, troposphere absorbs most of the heat radiated by the Earth's surface, thereby, maintaining the temperature of the surface.

This layer contains dust particles and water vapour. All changes in climate and weather take place in this layer.
Why is the tropopause important?
The tropopause is an important boundary layer in Earth's atmosphere dividing the lowermost atmospheric layer, the troposphere, from the stratosphere.
What is the temperature in the troposphere?
As the density of the gases in this layer decrease with height, the air becomes thinner. Therefore, the temperature in the troposphere also decreases with height in response. As one climbs higher, the temperature drops from an average around 62°F (17°C) to -60°F (-51°C) at the tropopause.
